How do i fix my tool not saving the coins?

So I'm creating a tool to give me plus 1 coin so I created a data store leader stats it works fine i tested it with the developer console but it doesn't save the tool coins here is the data store leaderstats :

local DataStore = game:GetService("DataStoreService")
local DS1 = DataStore:GetDataStore("CoinsDataStore")

game.Players.PlayerAdded:Connect(function(plr)
	local leaderstats = Instance.new("Folder",plr)
	leaderstats.Name = "leaderstats"
	
	local Coins = Instance.new("IntValue",leaderstats)
	Coins.Name = "Coins"
	Coins.Value = 0
	
	Coins.Value = DS1:GetAsync(plr.UserId) or 0
	DS1:SetAsync(plr.UserId,Coins.Value)
	
	Coins.Changed:Connect(function(plr)
		DS1:SetAsync(plr.UserId,Coins.Value)
	end)
end)

##Tool script:

-- Tool Script that give +1 click when clicking a tool
local leaderstats = game.Players.LocalPlayer.leaderstats
local Coins = leaderstats.Coins
local Cooldown = false


script.Parent.Activated:Connect(function()
	if Cooldown == true then return end
	if Cooldown == false then
		Cooldown = true
		Coins.Value = Coins.Value +1
		wait(0.8)
		Cooldown = false
	end	
	end)

It's not saving my coins from the tool when i click i do get +1 coins but it dosen't and i have not problem with my datastore what did i do that it's not saving what i get from the tools.

I assume you're using a server script for this, if so, the value "LocalPlayer" is not replicated, this means only a local script can read it. If you're using a local script, use a server script or remote events (not reccomended, never trust the client.), a solution would be:

-- Creates empty variables to be edited later on. (This is a ServerScript)
local leaderstats 
local Coins
local Cooldown = false

local player
local character

script.Parent.Equipped:Connect(function() -- This will assign the values to the previously mentioned empty variables.
	
	character = script.Parent.Parent
	player = game.Players:GetPlayerFromCharacter(character)
	
	leaderstats = player:WaitForChild("leaderstats")
	Coins = leaderstats:WaitForChild("Coins")
	
end)

script.Parent.Activated:Connect(function() -- Once activated, change the value of Coins.
	if Cooldown == true then return end
	if Cooldown == false then
		Cooldown = true
		Coins.Value = Coins.Value +1
		wait(0.8)
		Cooldown = false
	end 
end)

Hope this helps!
